CARL FOGELBERG AND GEORGE WV. GRAVES, OF (JAHBRIDGEPORT, MASS, A SSIGNORS TO GEO. WOODS & 00., OF SAME PLACE.

. APPARATUS FOR MARKING NOTE-CYLINDERS FOR MUSICAL INSTRUMENTS.

SPECIFICATIGN forming part of Letters Patent No. 230,540, dated July 27, 1880.

Application filed March 24, 1880. (NomodclJ To all whom it may concern:

Be it known that -\\'e, CARL FOGELBERG and GEORGE GRAVES, citizens of the United States, residing at Gambridgeport, in the county of Middlesex and State of Massachusetts, havejointly invented certain new and useful Improvements in Apparatus for Marking Note-Cylinders for Musical Instruments; and we do hereby declare the following to be a full,

10 clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, and to the letters or figures of reference I 5 marked thereon. which form a part of this specification.

Our invention relates to a new and useful apparatus for marking note-cylinders for musical instruments. Such note-cylinders are generally provided with projecting metallic pegs and staples driven into the Wood of the cylinders and located on the peripheries thereof at proper intervals, so as to produce the desired tunes on the musical instruments in connec- 2 5 tion with which they are used.

The manner of carrying out ourinvention is illustrated in the accompanying drawings, in Which- Figure 1 represents a plan view. Fig. 2

represents a side elevation. Fig. 3 represents a cross-section on the line AB, shown in Fig. 1', and Fig.4 represents a modification thereof.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

it represents a wooden templet note-board, provided on its upper surface with note-projections b I) b b b I), as shown. The noteboard a is temporarily attached to the'later- 4o ally-adjustable plate or carriage 0, having a rack, c, on its under side, as shown, and capable of a sliding motion between suitable guides on the frame d by means of the pinion e and crank e, as shown.

f f are anti-frictional rollers, upon which the carriage c is supported, so as to be able to slide it Without much friction.

ings on the adjustable bars h IL, hinged to the frame (I at hh, as shown.

For the purpose of pressing down the notecyiinder g and holding it against the projections I) l) I)" on the templet a we use a pair of 5 leversyi t hinged att'i to thestationarystandards k k, the lower ends of which levers are made to bear against the ends of the bearingbars h h when the notecylinder g is being marked; but we do not wish to confine ourselves to such precise mechanism, as springs, screws, or other or similar well-known pressure devices may be used to equal advantage.

In Fig. 4 the rotary teinplet-cylinder Z, with its note-projections m m m, is shown as being 6 5 substituted for the sliding templct note-board In Figs. 1, 2, and 3 another modification is shown as consisting of the pencilor mai her a, secured to the end of the lever 0, that is hinged at 0, and provided with a downward- 7o projecting piece, p, jointed at p to the rocking lever q, that ishinged at q to the standardbrace k, and having in its outer end a tooth,

7*, that is made to rest on the templet a by the action of the spring 8, as shown. 5

t t represent staples or projections'on the templet a, which, when the latter is moved horizontally, cause the tooth r to rise and fall, and by the connecting mechanism, as above described, the pencil or marker at is also made to rise and fall, so as to produce corresponding notemarks, on the cylinder g when the latter is rotated either by means of a crank or other suitable mechanism.

To mark a cylinder it is therefore only necessary to bring it in contact with the projec tions on the tempIet-board a or templet-cylinder l, as described, and by moving them together with equal surface velocity it is easily perceived that the projections on the aforesaid o templet or templets produce corresponding marks g g g on the note-cylinder g, that serve as guides where to drive and locate the pegs or staples that act as note-projections.

The projections on the templet note-board a are shown as isolated sharp-pointed pegs b I) b, or in groups consisting of a pair of sharppointed pegs, b I), with asquare-headed peg, Z), arranged between them. The former that is, the pointed pegs I) b-serve to make impressions or marks on the note-cylinder to locate and drive isolated pegs or note-projections, and the latterthat is, the combination of the pegs b b b-serve to make impressions or marks for the location on the notecylinder of staples of the length of the distance between the sharp pegs b 2).

This our apparatus may be used equally well for making indenture or for printing marks on the note-cylinder. In the latter case it would only be needed to have all the projections on the templet of a flattened upper surface and to color them with suitable ink or color.

After a cylinder has been marked or indented as above described it is removed and the pegs and staples driven by hand, as usual. The operation may be repeated to mark or indent any number of cylinders required.

Having thus fully described the nature, construction, and operation of our invention, we Wish to secure by Letters Patent, and ,claim 1. The'within-described method of marking note cylinders for musical instruments, the same consisting in indenting or marking a cylthe marker or pencil at, its lever 0, connectingbar 1), and lever q, with its projection r and spring 8, and a templet board or cylinder or its equivalent, as and for the purpose described. In testimony whereof we have affixed our signatures in presence of two witnesses.
